The last roof.The next chapter.

An Interlock roof is engineered as a lifetime system and backed by the Guardian Lifetime Limited Warranty — lifetime coverage for the original owner, transferable with 50 years of coverage for the next owner. Most homeowners never roof again.

Pricing depends on your roof’s size, pitch, complexity, and the profile and color you choose. An Interlock roof costs more upfront than asphalt but never needs replacing — paying for itself through decades of zero re-roofing costs and lower energy bills.

Yes. Every Interlock roof includes a lifetime limited material warranty covering the original owner for as long as they own the home, and it transfers one time to the next owner with 50 years of coverage — a documented selling point when your home goes to market.

Yes. Interlock systems carry the UL 2218 Class 4 impact rating — the highest hail-resistance rating available — withstanding a 2-inch steel ball dropped from 20 feet without cracking or splitting.

No — the opposite. The Alunar® Coating System uses Cool Roof ceramic IR-reflective pigments that reflect solar energy, and Interlock roofs are CRRC rated, helping reduce attic temperatures and summer cooling costs by up to 25%.

No. Interlock roofs install over your existing deck and underlayment, so rain noise is comparable to — often quieter than — an asphalt roof.

Yes. Aluminum doesn’t crack, split, or lose impact resistance through freeze-thaw cycling, and the interlocked panels shed snow and resist ice damming. The same Interlock aluminum construction was selected for a research station in Antarctica.

Yes. Interlock systems carry Florida Product Approval FL7263-R7 under the Florida Building Code, are tested to UL 580 / TAS 125 wind uplift standards, and are warranted to resist wind speeds up to 120 mph.
